My invention relates` to elevators andi particilarly to closed car elevators used. to convey passengers in stores and voffice buildings.

The most important objectief my invention is to increase the eiiiciency o'i` elevator operation in terms of loading. and unlading time, or trips per hour, and operator eiciency.-

Another obiect of my inventionis to secure maximum safety ofv elevator operation.

The most importantffeature of my invention izesides in an elevator car having an entrance as wide as the passenger space within it,. thus eliminating the crowding and jostl'i'ng 'incident to the operation of conventional cars' in which the ezitrance is constricted to less than hall?.` the width of.' the passenger space..

Another feature o`f` the invention consists in the provision `oi"`sepa`rated compartments for the operator and the passengers, the operators booth being raised above the iloor level of the passenger compartment, not onlyto free .the peratr from passenger interference .but also to afford him a clean, unimpeded. view of the car and the area adjacent the elevatr doors on each floor oftl'ie building.

the building assigned ffelvatbr' Shafts is iie usefully employed, Apassengers receive faster service, and operator fatigue is reduced to a minimum. 1

These and other'objects `and features ol the invention, together with incident advantages', will more readily he understood andappre'cated from the following detailed description of a preferred` embodiment thereof selectedfor purposesof-illustration and shown in the accompanying drawings, in which:

Fig. 1 is a view in horizontal cross section of an elevator constructed in accordance with my invention, and

Fig. 2 is a View in perspective of the elevator. the roof being largely broken away to expose the interior.

As shown in Fig. l the elevator of my invention is disposed in a well or shaft of a building, the shaft being defined by walls shown in broken lines at Ill. An opposed pair of vertical girders I2 serve as guides along which the car slides. The mechanism for raising and lowering the car forms no part of my invention and is not shown in the drawings.

'Trie elevator' car is constructed of steel, 'wood or" combinations thereof and includes a' full length rear wall I4, and end walls It and' I8, allv sup*-A p'crted on a door 2e and covered by' a roof 2 2. The ccr 2b extends forwardly or the end'waiis i and it to forni a ledge 24* running acrosstne full' width ofthe elevator and extending laterally beyond tlie wall It by an amount equalling ap-- proxrnately one fftli of the' distance between the end walls It and f3. i

A partition te extends `forwardly from 'the` rear wall I4 parallel to the end Walls and spacedirom the wall ib'y'an amount also eeuailing one fifth of the distance between the end walls le and M. At the vliront ofV tlie cai" ktile partition 3i? is* cut" away' to form an alccx'nf: orV booth barbed by-a short transverse wall'and provided withalioor 34 raised a foot or more' above the level of the floor 29. Within the booth a seat Seis 'mounted' on the short vv'aH 32, and the front ofv the booth is formed by a second Short transverse' wail' 3# again equa-l in widtlflv tojone fth the' distance between the end vwalls' -t and I. oor cori# trolling mechanism 4c is securedtc the inne-r sar-f face 4of the wail 3`8' Iand disposed at a VheightV convenient for an operator-occupying the booth;

It will be evident' that the car provides" senger space" onv the Hoor 26 Awhich is separated from the operators beet-ii and tha-ttlreie isnt front wall which covers any portion of the* Seng-er' area. Inasmuen as` laws andcrcffinances usually require that elevators be `previcied doers, I' employ two pairso `sliding' doors of which is equalin widtlfi teer-re quarter ofi the distance from tllieendi wall fre tothe partities 3d'. @ne pair et and 521 epee @shown lines) stand in completely overlapped-relances@ nichty cf the Wallet formstne -orwafderid of the operators booth. The other pair-of doofe 54-fand5l", when cpel,l `'are also cernpletelyioverlapp'ed'and stand crt the lateral extension or trie ledge 24.

When the doors are to be closed the doors 5D and 54 advance toward each other to close the quarter spaces adjacent the sides of the opening, while the doors 52 and 55 are advanced further until they meet and close the inner quarters of the opening. The closed position of the doors is shown in broken lines in both figures. The door operating mechanism forms no part of my invention and is not shown on the drawings.

It will be observed that there is a small enclo sure B formed by the walls I4, I8, 30 and 32. The enclosure BD may be utilized for storage of various articles or used as a clothes locker for l 3 the operator, a suitable access door (not shown) being provided.

At each floor of the building I provide pairs of sliding doors 10 and 12 (shown in broken lines) and a mirror 'I4 disposed on the jamb to aiord the operator a view of conditions out of range of direct View.

It might be thought that the maximum space for passengers is not fully employed by the arrangement shown and described, because of the lateral extension of the ledge 24 and because of the space occupied between the partition 36 and the wall i8. However, nothing is lost because of the extension of the ledge, since adjacent ele-Y vators cannot practically be disposed so closely together as to make that space available. Moreover the space occupied by the operator is no more than is required in conventional types. The great decrease in loading and unloading time effected by the full front opening more than compensates for the loss to passengers of the enclosure 60.

In addition to speeding up the operation of the elevator, the arrangement of my invention reduces the jostling of the passengers and renders the service more comfortable. The operator is not only protected from crowding but is also raised to a commanding position in which he has better control of the elevator, better vision, and is less subject to fatigue because the work is easier.

Variations from the arrangement shown and described will suggest themselves to those skilled in the art, but the invention is not limited to the details herein shown but is to be measured by reference to the appended claims.

Having now described and illustrated a preferred embodiment of the invention, what I claim as new and desire to secure by Letters Patent of the United States is:

1. An elevator comprising walls forming a car entirely open at one side, a booth adjacent said open side and raised above the level of the car iioor, and a plurality of opposed sliding doors carried by the car and movable either entirely to cover or entirely to expose said open side.

2. An elevator as defined in claim 1 wherein door controlling mechanism is disposed in said booth.

3. An elevator comprising a iloor, rear and 'l side walls disposed on said oor, walls forming a booth adjacent one of said side walls, the Width of said booth being approximately one fth the distance between the side walls, and opposed sliding doors arranged to move across the floor tially rectangular enclosure, walls forming a booth adjacent one of said side walls, a second oor for said booth raised above the level of said first iioor, and doors arranged to cover or reveal the fourth side of the rectangular enclosure.

5. An elevator car comprising walls forming an enclosure having a oor and side walls, an

vopening in one side of said enclosure, partitions dening an elevated compartment at one end of said enclosure adjacent said opening, said partitions being constructed and arranged to denne within the car a chamber communicating with the opening and substantially as wide as said opening, and two opposed pairs of doors mounted on the car and movable from a retracted position in which said opening is entirely unobstructed to an extended position in which the opening is entirely closed.

6. An elevator car comprising walls forming an enclosure having a floor, and side walls, an opening in one side of said enclosure, partitions dividing the enclosure into an elevated compartment adjacent the opening and a chamber communicating with the opening and substantially as wide as said opening, and two opposed pairs of doors mounted on the car and movable from a retracted position in which said opening is entirely unobstructed to an extended position in which the opening is entirely closed.

7. An elevator car comprising a compartment formed by a iioor and a plurality of side walls with an opening extending across one side of said compartment, opposed doors movable from a position at either side of said opening in which said opening is completely unobstructed to a position in which said opening is fully closed, and walls forming a booth disposed adjacent to and communicating with said large compartment, said booth having a oor elevated above the level of the large compartment.

8. An elevator car comprising walls and a oor forming an enclosure, one side of said enclosure being open, means for closing and opening said open side of the enclosure, said means being so constructed and arranged as to present no obstruction to access to the enclosure when in the open position, and partitions and an elevated oordefming a compartment at one end of said enclosure adjacent said opening and communi eating with said enclosure.
